Burns
This equipment contains high temperatures and burning laser radiation which could cause 2
nd
degree burns . Do not attempt to
remove any protective panels . There are no user serviceable parts inside .
If a burn occurs, seek first aid and immediate medical attention. Pushing the E-stop button will de-energize the equipment and
diffuse the hazardous situation .
Electrocution
The SLS system contains equipment energized at 208 volts, 3-phase delta . Do not attempt to remove protective panels . There
are no user serviceable parts inside .
If electrocution occurs, seek first aid and medical attention immediately. Pushing the E-stop button will de-energize the
equipment and diffuse the hazardous situation .
Material Inhalation
The part cleaning process may create a choking or air restriction hazard. If someone has difficulty breathing or a “loss of
breath” sensation, transport the person to a well-ventilated room or outside of the facility . If the condition persists, seek
immediate medical attention .
SLS EQUIPMENT SAFETY FEATURES
A major design goal for all SLS equipment is to provide a safe operating environment . The frame and enclosure designs
passively limit hazardous access while the electronics and software actively and automatically sense and react to unsafe
conditions when they arise . For example, if the SLS system detects unsafe operating conditions, it will immediately stop
operating and, in some cases, shut down completely .
CAUTION: If any SLS equipment safety features fail, your actions may be all that will prevent
potentially hazardous operating conditions.
Safety Interlocks
Safety interlock devices on the SLS equipment help prevent accidental laser exposure, electrical shocks, crush injuries, burns,
and fires. SLS equipment will not operate unless all safety interlocks are satisfied.
CAUTION: Never try to disable or override any safety interlock device on any SLS equipment.
Operating equipment without all safety interlocks enabled can cause equipment damage, injury, or
death. If you suspect a safety interlock device is not working properly, do not operate your SLS
equipment. Rather, disconnect power from the equipment and contact 3D Systems Customer Support for
assistance.
a. Internal panels are for service access only. Several interlocked panels are for customer maintenance: overflow cleanout,
blackbody cleaning port, and the filter box located on back of machine.
Limited Access and Barrier Shielding
SLS equipment frame and enclosure designs limit access to the following:
•
Service areas
, such as cabinets and enclosures for electrical power and automation controls. This prevents
accidental exposure to electrical shock hazards.
•
Material areas
, such as material feed hoppers, storage bins, and transport tubes. This prevents:
•
burn hazards by minimizing exposure to heated material
•
slip hazards by keeping material from dropping on the floor
•
fire hazards by minimizing airborne dust cloud formation and potential ignition. See SDS for complete
material hazard details.
